The Department of Homeland Security has seized a domain name registered outside of the US, by individuals who are not American citizens, and who registered with a Canadian registrar.

What is unique about this case is that the American authorities did not get the domain's registrar - a Canadian company - to pull the domain. Instead they went to Verisign, which operates the entirety of .com, and had them pull the glue records, the warrant states.

By going to the root operator of .com and having the records pulled - bypassing the registrar entirely - the DHS has sent the world exactly one message: anything hosted in the US, registered in the US, or using a domain whose root is controlled by a US corporation is subject to American law.
